XMLMember SciFigs::ImageLayer::ReferencePoint::xml_member

(

XML_MEMBER_ARGS

)

[protected, virtual]

Re-implement this function to offer XML restore (children and properties) support to your class.

From tag and map (with contains the attibute value) return a unique identifier under the format of a XMLMember. XMLMember is initialized with 3 types of contructors:

• An integer: id number of a property
• A XMLClass * : a child of this object identified by tag
• Default constructor: error, unknow child or property

Map of attributes can be inspected in this way (can be achived also in xml_setProperty()):

    static const QString tmp("childrenName");
    XMLRestoreAttributeIterator it=map.find(tmp);
    if(it!=map.end()) {
      // found attribute "childrenName"
    }

If the map of attributes is not used:

    Q_UNUSED(attributes);
    if(tag=="x1") return XMLMember(0);
    else if(tag=="y1") return XMLMember(1);
    else if(tag=="x2") return XMLMember(2);
    else if(tag=="y2") return XMLMember(3);
    else return XMLMember(XMLMember::Unknown);

Arithmetic operations + and - apply to XMLMember to avoid confusion of property id numbers between inherited objects. Offset 3 corresponds to the number of properties defined in this object.

    if(tag=="anInteger") return XMLMember(0);
    else if(tag=="aString") return XMLMember(1);
    else if(tag=="aDouble") return XMLMember(2);
    return AbstractLine::xml_member(tag, attributes, context)+3;

For the arguments of this function use Macro XML_MEMBER_ARGS.

Reimplemented from QGpCoreTools::XMLClass.

References TRACE.

{
  TRACE;
  Q_UNUSED(context);
  Q_UNUSED(attributes);
  if(tag=="name") {
    return XMLMember(0);
  } else if(tag=="image") {
    return XMLMember(1);
  } else if(tag=="real") {
    return XMLMember(2);
  } else {
    return XMLMember(XMLMember::Unknown);
  }
}

bool SciFigs::ImageLayer::ReferencePoint::xml_setProperty

(

XML_SETPROPERTY_ARGS

)

[protected, virtual]

Re-implement this function to offer XML restore properties support to your class.

From memberID set the corresponding property with value content. The map of attributes is given as a supplementary information (not useful in all cases).

For a general case:

  Q_UNUSED(attributes);
  double val=content.toDouble();
  switch (memberID) {
  case 0:
    _x1=val;
    return true;
  case 1:
    _y1=val;
    return true;
  case 2:
    _x2=val;
    return true;
  case 3:
    _y2=val;
    return true;
  default:
    return false;
  }

For classes inheriting other classes (see also xml_member())

  switch (memberID) {
  case 0:
    _anInteger=content.toString();
    return true;
  case 1:
    _aString=content.toInt();
    return true;
  case 2:
    _aDouble=content.toDouble();
    return true;
  default:
    return AbstractLine::xml_setProperty(memberID-3, map, content);

For the arguments of this function use Macro XML_SETPROPERTY_ARGS.

Reimplemented from QGpCoreTools::XMLClass.

References QGpCoreTools::Point2D::fromString(), TRACE, QGpCoreTools::Point2D::x(), and QGpCoreTools::Point2D::y().

{

  Q_UNUSED(context);
  Q_UNUSED(tag);
  Q_UNUSED(attributes);
  switch(memberID) {
  case 0:
    _name=content.toString();
    return true;
  case 1: {
      Point2D p;
      p.fromString(content.toString());
      _image.setX((int)round(p.x()));
      _image.setY((int)round(p.y()));
    }
    return true;
  case 2:
    _real.fromString(content.toString());
    return true;
  default:
    return false;
  }
